What are Coral Reefs ?
• located in coastal zones of tropical oceans • formed by mutualism between polyps & algae • polyps secrete hard limestone deposits that remain when polyps die • Limestone = calcium carbonate = CaCO3
Dr. PARVISH PANDYA’s presentation
Corals are Animals Phylum : Cnidaria
“plant-like” animals symbiotic algae zooxanthellae Dr. PARVISH PANDYA’s presentation
Coral Reefs Importance:
Coral Biodiversity
• high biodiversity, like “tropical rain forests of ocean” • Removing of CO2 from the atmosphere • protect coastlines from storms & high waves • nurseries for many fish species • disappearing
Dr. PARVISH PANDYA’s presentation
Problems : Bleaching Coral Bleaching The algae within the corals die off. WHY? • Runoff of silt increases water turbidity and thereby prevents photosynthesis. • Increase in water temperature and UV radiation leads to physiological stress. Consequences Unable to grow, and repair leads to dieing of coral reefs. • Currently over 60% of the world’s coral reefs are threatening by human activities. Dr. PARVISH PANDYA’s presentation

Corals need: • warm water • clear water • nutrient-poor water Dr. PARVISH PANDYA’s presentation
Vulnerability & Human Impacts Vulnerability: • slow growing • easily disturbed • thrive only in clear water Human Impacts: • sediment runoff & effluent • increased UV radiation • fishing with cyanide & dynamite
